ADVANCED CHEMISTRY FOR MUNICIPAL & INDUSTRY
As blue green algal blooms become more frequent, management of them has become more critical.
Treatments have become more complex and expensive – think mechanical aeration and ultrasonic sterilisation.
Earth Science Laboratories took a different approach.
What if traditional and simple algaecides could be made dramatically more effective?

58% less copper dosage to treat freshwater green algae
Recent research shows how much less copper dose is required to effectively treat algae using EarthTec versus copper sulfate.
This graph shows the percentage inhibition rates of algae growth after 96 hours of exposure to copper delivered as conventional copper sulphate compared to EarthTec.
Using a conventional copper treatment (CuSo4.5h20), nearly two and half times the copper dosage was needed to achieve the same algae inhibition.
The tests were performed by Aquatic BioAssay and Consulting Inc., against the indicator algal species, selenastrum capricornutum, according to standard bioassays of chronic exposure, 96 hours.
Global warming has increased frequency of algal blooms. Increased use of copper sulphate isn’t the answer. If traditional copper sulphate is used, copper can build up over time, impacting marine life, and algae can develop a tolerance.
A fundamental rethink of how to make algaecides more effective and less harmful.
